150π m²
Step-by-step explanation:
Given:
Height(h) of Conical tent = 3.5 m
Base Radius(r) = 12 m
To find:
How many square metres of Canvas is required?

Easy to Solve, But How?
1. Analyse the Data i.e Question
2. Whenever you see [unit² Canvas] it's mean you have to find lateral Surface Area.
3. As h and r are present we have to find slant height (l).
4. Formula Related to Cone will use.
Solution:
As we know,
Hence, Slant Height is 12.5 m.
Now,
Lateral Surface Area = πrl unit²
= π × 12 × 12.5 m²
= 150.0π m²
= 150π m²
Therefore, 150π m² of Canvas is required.
Formula Related to Cone
Lateral Surface Area = πrl
Total Surface Area = πr(r + l)
Volume = 1/3 πr²h
Here, r is radius , h is height and l is slant height for any cone .
